▎ 摘  要

NOVELTY - Multi-functional composite particulates for lithium battery, comprises at least one of said composite particulates has a diameter from 50 nm to 50 mum and comprises multiples of anode active material particles that are dispersed in a high-elasticity polymer matrix having recoverable tensile strain no less than 5%, when measured without an additive or reinforcement, and lithium-ion conductivity no less than 10 to the power of -8 S/cm at room temperature, polymer matrix forms continuous material phase. USE - Multi-functional composite particulates for lithium battery. ADVANTAGE - Multi-functional composite particulates has conductivity, flexibility and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method of manufacturing the composite particulates, involves (a) Dispersing multiple particles of an anode active material in a precursor polymer solution to form a suspension wherein these particles are fully embedded or immersed in said precursor solution, which comprises a polymer dispersed in a liquid solvent or a liquid mixture of one or a plurality of monomers, an initiator or catalyst, and an optional curing agent; and (b) Operating a secondary particle forming procedure to shape the suspension into multiple droplets and remove the liquid solvent or polymerize and crosslink monomers to form said composite particulates wherein a particulate comprises a plurality of anode active material particles fully dispersed and embedded in a polymer matrix.
